Safety cage for high suction industrial vacuums

Abstract

The present invention discloses a safety cage for high suction industrial vacuums. The cage is fabricated from an open perimeter structure having an open end and intake end. Proximate the intake end there is an end guard which serves to prevent large objects from being sucked into the opened end of the cage. Flanges are provided at the open end to engage the intake of the hose. The perimeter structure is created from the cage rings and cage supports which form a rigid perimeter structure which keeps the hose from collapsing. A end guard is provided on the side of the perimeter structure to allow easy manipulation of the cage. Holes in the perimeter structure provide for receiving set screws which engage the side wall of the vacuum hose.

What I claim is: 
     
       1. A safety cage for a high-suction industrial vacuum having an elongated hose comprising: a. a perimeter structure having an open end adapted to receive a section of the hose at an open end of the hose whereby a wall of the hose is in a fixed position internal to the structure and an intake end opposite the open end and adapted to receive an edge of the hose wall at the open end of the hose; and   b. a end guard attached to the perimeter structure proximate the intake end.   
     
     
       2. The safety cage of claim 1 wherein the perimeter structure comprises an open frame having void areas. 
     
     
       3. The safety cage of claim 2 wherein the open frame comprises a plurality of cage rings transversely attached to multiple horizontal cage supports. 
     
     
       4. The safety cage of claim 3 further comprising attachment means to removably secure the cage to the wall of the hose. 
     
     
       5. The safety cage of claim 4 wherein the attachment means comprises adjustable screws which pass transversely through the frame to engage the wall of the elongated hose. 
     
     
       6. The safety cage of claim 5 further comprising locking means to receive and engage the end of the hose wall at the intake end of the hose to prevent further longitudinal movement of cage the along the hose and to reinforce the wall of the hose at the intake end. 
     
     
       7. The safety cage of claim 6 wherein the locking means comprises a plurality of flanges attached to the frame proximate the intake end of the frame. 
     
     
       8. A safety cage for a high-suction industrial vacuum having an elongated hose comprising: a. a perimeter structure having an open end and an intake end, the perimeter structure formed from cage rings and connecting cage supports, the rings and the supports defining voids in the perimeter structure, the perimeter structure having threaded holes for receiving set screws which engage the elongated hose whereby the hose is retained in a fixed position inside the cage;   b. an end guard attached to the perimeter structure proximate the intake end to prevent large items from entering the elongated hose;   and   c. a plurality of flanges attached to the perimeter structure proximate the intake end to receive an edge of intake end wall of the elongated hose.   
     
     
       9. A safety cage for a high-suction industrial vacuum having an elongated hose comprising: a. a rigid perimeter structure having an open end and an intake end, the perimeter structure having plural rings joined by plural supports to define a cage that receives and secures a section of the hose at an open end of the hose in a fixed position inside the cage; and   b. an end guard attached to the cage at the intake end and extending away from the open end of the hose.   
     
     
       10. The safety cage of claim 9 wherein the perimeter structure includes means for receiving set screws which engage the elongated hose. 
     
     
       11. The safety cage of claim 10 further comprising plural flanges attached to the perimeter structure proximate the intake end to receive an edge of the open end of the elongated hose. 
     
     
       12. The safety cage of claim 9 further comprising a handle attached to and extending away from the perimeter structure.
